Suppose that an economic agent is (1-\varepsilon) \times 100% certain that uncertainty she faces is characterized by a particular probability measure, but that she has a fear that, with \varepsilon \times 100% chance, her conviction is completely wrong and she is left perfectly ignorant about the true measure in the present as well as in the future. This situation is often called " varepsilon -contamination of confidence." The purpose of this paper is to provide a simple set of behavioral axioms under which the decision-maker's preference is represented by the Choquet expected utility with the varepsilon -contamination of confidence.
